China has mobile ordering to the next level. Every McDonald’s has a set of two sided lockers, you just scan your order QR code and the locker your order is in opens…no human contact what so ever.
In the USA, McDonald’s app is pretty bad compared to Starbucks at least. Nowhere near where it is in China (well, if you do the wechat plugin). I find it isn’t worth the trouble and will just use the kiosk for the rare times I still go there.
